Replacement Grease Cap for Harbor Freight Trailer  


Hello there! I have a Harbor Freight Super Duty utility trailer part #69897- would you know what size grease caps fit this trailer? Thanks!


Expert Reply:

Harbor freight trailers typically use metric bearings, which can make finding replacement bearings, grease seals and grease caps pretty challenging. You could very well find that you'd need to contact Harbor Freight directly.

To see if anything we offer would work, use an accurate measuring tool like a digital caliper, and measure the inside diameter of the hub bore where the grease cap would insert. Click the link I've provided, and see if the diameter of any of our available grease caps matches your measurement.
